Huo Ying: How to evaluate the past lives of "Spiral Pill"?
There is often a saying in Huoying that describes the protagonist, that is, a meatball is rubbed from the beginning to the end, and this meatball naturally refers to a spiral pill. Spiral Pill is Naruto Uzumaki's signature ninja, and it is also his most powerful ninja. There are many stories hidden behind Spiral Pill, and it is not an ordinary A-level ninja.
In fact, as early as Ootutuki Hagoromo's time, there was a rudiment of spiral pills. When Indra, Ootutuki Hagoromo's eldest son, and Asura, his youngest son, succeeded to the throne of Renzong, Asura used similar Ninjutsu.
At that time, the endurance technique used by Asura was a ball-shaped chakra ball. In fact, this chakra ball was an attack that condensed chakra together, which was different from the spiral pill.
In the plot, spiral pills are also constantly upgraded. At first, they are the most common spiral pills, then the Dayu spiral pills that Naruto mastered after following Jiraiya for two years of practice, and finally Naruto joined the spiral shuriken after attribute changes. Moreover, there are all kinds of spiral pills in the theatrical version, which can explain that spiral pills are a kind of endurance that accompanied Naruto's life.
The original inventor of Spiral Pill was Namikaze Minato of four generations of Huo Ying. According to Watergate, it took him three years to create his own ninja.
As soon as Chirabi saw the spiral pill, he felt very familiar with it, and guessed that the spiral pill was a ninja skill inspired by Bijyudama of four generations of Huo Ying. This guess is not unreasonable, because the nature of the spiral pill is really similar to that of Bijyudama, and Naruto can master Bijyudama so quickly because of his experience in practicing spiral pills.
The active period of the fourth generation of Huo Ying was during the Third Endurance World War. Since this is the Endurance World War, it is natural for all ninja villages to use the final weapon bijuu. Therefore, it is likely that the fourth generation of Huo Ying wanted to invent a Ninjutsu based on Bijyudama because he saw Bijyudama on the battlefield, and this Ninjutsu is a spiral pill.
Naruto, on the other hand, improved the spiral pill, which is not mature enough, and can only be regarded as a way of using chakra, without adding the attribute change of chakra. Naruto added the attribute change of wind attribute to download spiral pills under the guidance of Kakashi, which led to the birth of spiral shuriken.
In the fourth Endurance World War, after gaining the power of nine bijuu, Naruto can also use different spiral shuriken according to the different attributes of their respective chakra. In the final battle against Hyun Night, Naruto also used nine spiral shuriken with different attributes to give Hyun Night a huge surprise.
And the spiral shuriken in Huoying may not be the end of spiral pills. The essence of spiral pills is the endurance technique developed from Bijyudama, and the power of spiral shuriken is still far behind that of Bijyudama.
Bijyudama is actually an attack released by adding natural energy to chakra in bijuu, and it can be copied with Naruto's ability. Therefore, the final version of Spiral Pill should be Bijyudama, just because the conditions are harsh if you want to use Bijyudama, and only people can do it, so it is impossible to popularize it.
